- To'all whom/it may concern:

"Be it known that I,-'-'ZoLrAN TAM-ASS); a subject of Hungary, residing at Gleveland, in the county of Guy-ahogaand State of Ohiopha'veinvented certain'new'anduseful Improvements 5 in Automatic Speed-Controllisng Means for Engines,- of *whieh the following is a specification.

My 'inv'ention relates"to automatic. speed cont-rollingomeans for enginesyparticularly automobile engines, and the invention comprises an automatic devicepperatively connected with the engine and its throttle valve,

whereby the snpplyofpower fluid for the I engine may be definitely regulated and cut;

off at diiferent predetermined speeds of -the engine, substantially as herein shown and. described and more particularly pointed out in the claim. v p In the-accompanying drawings, Figure 1 is a side view of an automobile engine showing my invention incorporated therewith.

Fig. 2 is a sectional view centrally through the governor portion of the device, and Fig.

parts, but at right angles to Fig. 2. 8

As shown, the invention is applied to an internal combustion engine 2 having a carburete-r 3 to supply air and gasolene as A throttle valve14 is also shown, which is representative of the usual device or devices for regulating the vapor supply to the engine, and whereby the power and speed thereof may be constantly under hand 5 or foot control through a link or rod connection 5 which leads to the seat of the vehicle. Now, my object is to supplement the foregoing means with an automatically-operated throttle valve 6. placed in the line of intake t pipe 7 which connects carbureter 3 with the engine. This valve 6 controls the amount of vapor passing to thejengine independently of the usualthrottle; but does not operate except at predetermined intervals.

In simple terms,;my object is to fix any one of several maximum speeds at which the vehicle may be operated, and to accomplish this. purpose I connect a ball governor 8 with the arm 9 -.of=throttle valve 6 by link 0 10, which isattached to arm 11 of 'a short shaft 12 which projects from the globular casing 13 confining the governor 8. The

inner end of the shaft 12 has aslotted arm or arms 14 engaged with a trunnion or trunnions 15 on a free ring 16 within the annular recess, of rotatable collar 17, which -and the engine found to run satisfactorily ia-also slidably sleeved on tubular shaft 18. This shaft isdriveri from and=by the power parts of engine2'tl1uough'bevel gearing 19 and eountershaft QO;'or by any other *suit- 0' -*able"p'ower "connections, such as flexible --shafting @bviouslm wlr'en the engine 2' is running, shaft 18 is also runningv at a corresponding speed. Therefore, ball governor 8 which is 65 ==connected to shaft 18 f by lurks 21: and collar 22 willr also be rotated, Y but it is not my 1 intention to: have valve- 6 respond immed iately to the rotation of shaft 18, or to be sensitive thereto duri ng-the ordinary operation of 1d the'engme, excepting when predetermined maximum speeds are exceeded. Then and only then will the governor 8 be permitted to perform its functions under the centrifugal action of its balls 23 and whereby collar 17 is lifted and shaft 12 rotated by arm 14. At all other times the liftmovement of the governor is held in check by means which comprises both a spring and a counter weight,the spring 2 1 being contained 30 within the upper end of tubular shaft 18 'whereit rests upon a T-shaped member 25 which has lateral arms projecting through slots 26 in the sides of shaft 18 and bearing down upon collar 17. The upper end of 85 the spring has a loose head 27 which is engaged by a thumb screw, adjustably'secured in the upper end of shaft 18 and wherewith more or less tension may be given to spring 24. A cap or cover 29 is screwed upon casing 13 to conceal and protect the screw 28, so that its adjustment may remain undisturbed. J i

' The counterweighted means for controlling the action of the governor comprises an 95 arm 30 secured to the outer end of shaft 12 and upon which a counterweight 31 is free 7 to slide and to be set by. set-screw 32 at different distances from theshaft '12, and as marked thereon by notches 33. Of course 1 spring 24 and counterweight 31 co-act to check ,the up-lift' of governor 23; but the spring is more particularly intended to re main undisturbed after it has once been set under certain conditions. On the other, hand, the counterweight 31 is placed outside.

of casing 13 where the operator of the ma chine may adjust it at any time to. fix the maximum power and speed to be obtained from engine'2. Q

To illustrate, let us assume that the maximum speed (measured by the speed of the vehicle) is to be fixed at thirty miles per hour; then counterweight 31 I would be placed and set as shown in Fig. 3 at the notch having indicating mark 30. Whereupon, in operation, governor 8 Will not respond to the movement of the engine until its speed reaches the thirty miles fixed as.

'is thus diminished or cut off temporarily, the speed of the engine will be correspondingly influenced, and no greater speed than that predetermined can be obtained.

What'I claim is: v

In means for automatically limiting the speed of a driven part, a spherical casing, a tubular shaft vertically disposed in said casing, a ball governor mounted on said shaft and rotatable Within said casing, a spiral spring confined in said shaft and means at its top to fix the tension thereof, a collar slidably mounted on said shaft and bearing against the lower end of said spring and the said governor connected with said collar in lifting relations, and a countemveighted arm engaging said collar and adapted to resist the action of said governor when, running within predetermined maximum speeds, the said arm and the said spring being combined in function to resist the action of the said governor and the said arm having its counterweight outside the said spherical casing. In testimony whereof I afiix my signature in presence of two Witnesses.
